In Germany March 8, 1937 18 Claims.

The present invention relates to a lifting up I device or operating depth adjusting means for farming machines such as machines for harvesting potatoes, beets, turnips etc., more particularly to machines of the type set forth in which the frame is lifted or lowered by means of revolving the cranked axles which carry the running wheels and the support wheel respectively in order to produce the required operating depth of the machine.

An object of the present invention resides in the provision of a lifting up mechanism, particularly for machines of the type set forth, whereby the operating mechanism of the cranked axle of 16 the support wheel is simplified and can easily be supervised and whereby the vertical motions of the machine frame are definitely controlled.

It is an object of the present invention to provide a lifting up. or operating depth adjusting means in machines of the type set forth, whereby the cranked axle of the support wheel extends to and is connected with the cranked axle of the running wheels and is provided at its free end with a crank arm which is operated by an adjusting spindle which is movably guided by means of an arm which is rigidly connected with the cranked axle of the running wheels and which spindle rigidly yet adjustably connects both said cranked axles.

A further object of the present invention resides in the provision of lifting up or operating depth adjusting means in machines of the type set forth, whereby the axle of the support wheel is cranked and can be turned for operating depth 35 adjusting purposes independently from other operating depth adjusting means whereby desired cooperation of all operating depth adjusting and lifting up means is obtained.

It is a further object of the'present invention 40 to provide a machine of the type set forth in which the axle for the running wheels and/or the axle for the support wheel is cranked and in which the frame of said machine comprises tubular elements which are also used for housing said axle or axles.

Further and other objects of the present invention will be hereinafter set forth in the accompanying specification and shown in the 50 drawings which, by way of illustration, show what I now consider to be a preferred embodiment of my invention.

In the drawings:

Figure 1 is a diagrammatic side view of the .55 parts of a machine which constitute my present invention, the machine frame being in lowered position.

Figure 2 is a top view of the machine parts shown in Fig. 1.

Figure 3 is a schematic illustration of various operating positions of the machine parts shown in Figs. 1 and 2.

Figure 4 is a side view of a machine as shown in Fig. 1 with the axles housed in tubular frame elements.

Figure 5 is a top view of the machine illustrated in Fig. 4.

Like parts are designated by like letters in all figures of the drawings.

Referring more particularly to Figures 1 to 3 of the drawings rigidly connected members a and 12 make up part of the frame of the machine to which the present invention is applied. Member 0. serves for revolvably carrying the cranked axle c of the running wheels (1; member b which is connected at an angle to member a and extends at a slant rearward carries the cranked member f to which the support wheel h is movably connected; member 1 extends into the neighborhood of the running wheels and carries at its forward free end a crank arm 2'. Arm 1' movably carries at its free end a nut k through which the threaded spindle 1 extends; spindle I also extends through the nut m which is movably connected to the free end of arm n which arm is rigidly connected with the cranked axle 0. Thus the spindle l rigidly yet adjustably interconnects the axle c and the member I. The member 1, 3 is of L shaped configuration and comprises a short arm g having a cranked end portion to which the support wheel h is movably connected. The long arm J is movably connected with the structural member b.

A lever o is connected rotatably with axle c and has an abutment p which rests on crank arm a: of axle c. A nut q is rotatably connected with lever o and rotatably carries threaded spindle s which has a cranked end 8' and also extends through nut 1' which is swingably connected with frame member b. The frame a b is held in position by means of spindle s and the lever o with the abutment p resting on crank :r.

The members a and b may be of tubular configuration such as members u and t shown in Figs. 4 and 5 and the axle c and the member I arranged within said tubes u and t. Tubular members u and t are rigidly interconnected with one another as are members a and b in the embodiment of my invention according to Figs. 1 to 3. To make this connection more rigid an additional connecting member a is provided which revolvably carries 'the nut member r through which the threaded part ofthe spindle 8 extends. The other parts of the machine according-"to Figs. .4 and are exactly like the ones of the machine shown in Figs. 1 to 3 and designated by the same-letters. Since all parts have been described supra, a repetitionof such description is unnecessary.

The operation of the newlifting up device takes place as follows:

When revolving the threaded spindle s by manipulation of the cranked end s lever o with its nut q is moved downwards along the threaded part of spindle s andthereby swings about axle c; at the same time abutment p of lever o presses against crank 1', whereby axle c revolves counterclockwise about the axis of rotation 11 of the running wheels d whereby the frame part a and also part of b is lifted up. In the embodiment of my invention shown in Figs. 4 and 5, parts t and u are lifted up on manipulation of crank handle s.

Together with crank arm :1: also arm n which is rigidly connected with arm a: is moved and moves crank arm i upwards towhich it is connected by means of spindle l and joints m and It. When swingingv arm i upwards member! is revolved and arm 9 of member I pressed downwards; arm g carries support wheel h which rests on the ground so that by said downward pressure frame part b or in the case of the machine according to Figs. 4 and 5, part t is lifted upwards.

When operating, i. e. revolving, adjustment spindle 1, arm i is rotated independently from the cranked axle of the running wheels, whereby the frame adjacent to the support wheel h is lifted or lowered and the latter assumes an inclined position.

By lowering the frame the machine is lowered into operation position; by lifting it is brought into non-operating position.

In Fig. 3 the solid lines show the machine in lowermost position; the dash and dot lines show the machine in uppermost position and the dotted lines show the machine in an intermediate position, such as is obtained, for example, by operating the spindle 1.

While I believe the above described embodiments of my invention to be preferred embodiments, I wish it to be understood that I do not desire to be limited to the exact details of design and construction shown and described, for obvious modifications will occur to a person skilled in the art.
